PNH — Oryza sativa Japonica

Summary

OsPNH (OS02G0169400) on rice chromosome 2 encodes an Argonaute-family protein containing Piwi, PAZ, and RNaseH-like domains, with annotated siRNA and miRNA binding, DNA-binding transcription activator activity, and histone ubiquitin ligase activity. The gene is associated with reproductive growth, grain yield, and erect growth in rice, and has been linked to leaf polarity, leaf morphology, auxin signaling, TAS3 tasiRNA biogenesis, juvenile-to-adult transition, antiviral immunity, and virus resistance. It is associated with appendage development, gene silencing by miRNA, and regulation of body size. Associations also include grain yield, panicle length, amylose content, tiller angle, photosynthetic ability, and responses to UV light. Related genes in other species are linked to floral development, shoot meristem organization, and drought stress response.
